中文摘要:山东新汶矿业集团ZJ02—PJ02对接井，直井ZJ02设计深度为94112 m，斜井PJ02井设计深度为120300 m，两井相距25200 m。设计井身为三开结构并合理配置钻探及造斜专用设备；为防止井斜采用塔式钟摆钻具；根据不同井段，合理选用钻压、钻速和泵量，配制不同的钻井液；采用高精度的PST随钻测斜和最小曲率法计算钻井轨迹，保证了两井的顺利对接连通。

Construction Technology of Directional Butting Connection for Salt Well
Abstract:The paper introduced ZJ02-PJ02 butted wells of Xinwen Mining Group, the designed depth of the shaft and the inclined well were 94112m and 120300m, and these two wells was 25200m apart. The designed well structure was trisected with drilling and angle building equipment rationally installed. Tower-type pendulum drilling-assembly was used to prevent well deviation. Drilling pressure, drilling ratio, pumping volume and drilling fluid were selected according to the different situation in different well section, high precision PST MWD and minimum curvature method were applied to calculate the drilling trajectory to guarantee the butting of two wells.
